Also, it's highly person dependent.

I'm an obese american (lost 10% of my body weight in the last 7 months, so almost not obese anymore) who is 30+, but my testosterone has measured between 850 and 1400 in the last 7 months.

That probably helped with my weight loss, but I have a full head of hair still and am somewhat likely to keep it.

We'll likely spend longer measuring what the hormonal effects of PFAs and microplastics are than we'll have pfas and microplastics to deal with.
